DIY Frankenstein Halloween Costume Using Footed Pajamas

Make a Set of Neck Bolts from a Bent Coat Hanger, Cardboard and Tin Foil.

Cut the Hanger to size, bend it to fit the neck, place the cardboard bolt" end on the end of the wire, wrap the cardboard, then wrap the bolt" stem - then wrap the end of that piece of foil around the hanger.

Secure it with tape.

Make a Very Large Sport Jacket from Moss Green Felt (Felt is available in a 6 foot wide version for about $5 a yard from fabric stores).

Lay an existing loose-fitting jacket on your felt, cut around it (leave at least 4" - this has to fit over a footie pajama - and have stuffing added in the shoulders).

It's best to make a newspaper pattern first, then hold it up to your victim for sizing, so you don't cut your felt incorrectly...

Sew it together and place stuffing (toilet paper or newspaper) under the shoulders of the pajamas.
